That's funny Pacnorwest, but they can be trained to leave everything, we used to do that one at dog training and it wasn't ours that took the food and toys.
Thanks Sjoerd, it all depends on what they're fed with, if it was a dry food then it wouldn't be too expensive. But if it was a natural food then yes, but they don't need a lot. Yes they're supposed to like the water, so they're just waiting for the command from the owner.
My mate had this kind of dog, but she was very old and not nearly so energetic. It had such a good nature. It was fond of the water also, but too arthritic to get out in it.
